Subject: [PATCH v2] atomics,cmpxchg: Privatize the inclusion of asm/cmpxchg.h

After commit:

atomics: add acquire/release/relaxed variants of some atomic operations

Architectures may only provide {cmp,}xchg_relaxed definitions in
asm/cmpxchg.h. Other variants, such as {cmp,}xchg, may be built in
linux/atomic.h, which means simply including asm/cmpxchg.h may not get
the definitions of all the{cmp,}xchg variants. Therefore, we should
privatize the inclusions of asm/cmpxchg.h to keep it only included in
arch/* and replace the inclusions outside with linux/atomic.h
